How the 7216-BECBY model number is decoded
7216 BECBY is SKF's 80 mm-bore single-row angular-contact ball bearing in the 7200 series, nominal 40° (B) contact angle, 80×140×26 mm to the ISO dimension plan. 40° contact angle (suffix B): the steep standard single-row angle, giving the highest axial capacity at the cost of speed, with a recommended load ratio Fa/Fr ≥ 1. E marks the optimized internal design with an enhanced ball complement and race geometry. stamped brass cage, ball-centred (suffix Y) — lighter than the machined M cage but brass rather than polymer. CB means universally matchable with Normal axial internal clearance: the two side faces are ground so any two units form DB (back-to-back), DF (face-to-face) or DT (tandem) sets without regrinding. BECBY combines the optimized 40° geometry with CB universal clearance and a stamped brass Y cage. Envelope 80×140×26 mm (3.15×5.512×1.024 in), 30.0 mm radial section height, C 85 kN, C0 75 kN, Pu 3.05 kN.reference speed 5,600 r/min (thermal) and limiting speed 5,600 r/min (mechanical), which coincide for this size, catalogue mass 1450 g. At the printed limiting speed of 5,600 r/min the mean pitch diameter dm ≈ 110.0 mm implies a dn value around 616k mm·r/min; the 5,600 r/min reference speed is the thermal-planning figure under catalogue load. The 3.05 kN fatigue load limit is the equivalent-load floor for long-life adjustment; with 85/75 kN ratings and 1450 g mass this execution carries about 1.06 kN of C per millimetre of bore. Speed-ratio note for this exact unit: the reference speed is 5,600 r/min against a 5,600 r/min limiting speed, i.e. a reference-to-limit ratio of 1.00. Cage detail specific to this order number: the Y cage is stamped from brass strip into ball pockets rather than machined from solid, giving a lighter cage assembly and lower centrifugal mass than the M execution; it remains brass (temperature and oil-additive tolerant, unlike PA66) but is the formed-cage design, and the machined-brass BECBM order number remains the choice for severe shock or marginal lubrication.
Typical equipment & failure modes
Common applications
- medium and large machine-tool spindles
- industrial gearboxes and speed reducers
- process pump and compressor drives
Known failure patterns
- fretting at the ground set faces of a universal pair whose clamp torque relaxes
- raceway spalling from axial overload beyond the single-direction thrust rating
- ball skidding when Fa/Fr stays below the 1,0 (40°) or 0,55 (25°) ratio and the contact ellipse is unloaded
- stamped brass cage pocket deformation after shock loading beyond the lighter formed cage capacity
- edge loading from shaft deflection or housing misalignment
- mounting score marks when the bearing is cocked over a burr or keyway
Selection pitfalls — read before you substitute
- Keep the load ratio in the SKF design range: Fa/Fr ≥ 1 for this angle; below it the balls unload the contact ellipse and skid, which is why the catalogue insists on a minimum axial load (Fam ≈ A·(n·dm/1000)²) at high speed.
- Keep the load ratio in the SKF design range: Fa/Fr ≥ 1 for this angle; below it the balls unload the contact ellipse and skid, which is why the catalogue insists on a minimum axial load (Fam ≈ A·(n·dm/1000)²) at high speed.
- Preload the set against a calculated stand-off dimension — the ground faces of BECBY establish it, but locknut torque, sleeve crush and housing-face squareness each consume part of the allowance.
- Keep the load ratio in the SKF design range: Fa/Fr ≥ 1 for this angle; below it the balls unload the contact ellipse and skid, which is why the catalogue insists on a minimum axial load (Fam ≈ A·(n·dm/1000)²) at high speed.
- The steep 40° angle of 7216-BECBY favours thrust-heavy combined loads; for a predominantly radial high-speed position the 25° ACCBM execution of the same size is the alternative order number.
- Universally matchable BECBY bearings arrive ready for set mounting, not preloaded sets: preload results from how the set is clamped, so follow the SKF stand-off-ring and nut-torque procedure.
Frequently asked questions
What are the dimensions and catalogue data of 7216-BECBY?
7216 BECBY measures 80 mm bore × 140 mm OD × 26 mm width (3.15 × 5.512 × 1.024 in), mass about 1450 g. SKF 17000 ratings: C 85 kN, C0 75 kN, Pu 3.05 kN, reference speed 5,600 r/min (thermal) and limiting speed 5,600 r/min (mechanical), which coincide for this size.
What does the BECBY suffix mean?
40° contact angle (suffix B): the steep standard single-row angle, giving the highest axial capacity at the cost of speed, with a recommended load ratio Fa/Fr ≥ 1. E marks the optimized internal design with an enhanced ball complement and race geometry. stamped brass cage, ball-centred (suffix Y) — lighter than the machined M cage but brass rather than polymer. CB means universally matchable with Normal axial internal clearance: the two side faces are ground so any two units form DB (back-to-back), DF (face-to-face) or DT (tandem) sets without regrinding. BECBY combines the optimized 40° geometry with CB universal clearance and a stamped brass Y cage.
What do the reference and limiting speeds mean for 7216-BECBY?
The 5,600 r/min reference (thermal) and 5,600 r/min limiting (mechanical) speeds are catalogue conditions; preload, lubrication and heat removal move the permissible value, so re-calculate for the actual arrangement.
Can one 7216-BECBY take thrust in both directions?
No. A single-row angular-contact bearing reacts axial load in one direction; reversing thrust needs a DB/DF matched pair (use a universally matchable CB/GA execution) or a double-row bearing. Under radial load the 40° angle induces an axial force that the arrangement must balance.
